Digitalization potential in control cabinet building

From |
 control cabinet building

Control cabinet building can benefit from optimization through digitalization, lean management, and agility approaches. However, manual activities still dominate production, making automation difficult. Electrically skilled personnel are essential for wiring and adaptability, as they understand equipment requirements and can react to unforeseen challenges that cannot be mapped in a highly automated process.

The skills shortage exacerbates the problem

Traditional control cabinet building relies on well-trained electrically skilled persons for long-term success, and automation is limited. in addition, time is pressing to integrate the remaining electrically skilled persons into relevant production processes. Moreover, untapped potential in information flows and digital support exists, especially for small and medium-sized companies.

Weaken your weaknesses and strengthen your strengths

The saying “Focusing on strengthening your positive qualities and skills while trying to overcome your weaknesses” fits well the digitalizing of company processes. To implement this strategy, identify and categorize areas of the company based on their influence on the company’s success. These areas are typically technical and represent the company’s competitive advantage. The support categories include non-technical areas necessary for core competencies tasks, while organization categories include non-specific areas like HR departments. Introducing market-standard software can help digitalize these areas, addressing weaknesses. However, standard commercial software may leads to loss of unique selling points, impacting the company’s competitive advantage. The digitalization plan should consider practical requirements, employee needs, and company goals.

The role of detailed analysis

A thorough analysis of information flow is the first step towards optimizing. Understanding all work steps is essential to identify optimization potential. Digitalized worker assistance systems can help by directly supporting work steps with necessary data. However, ad-hoc integration and digitalization without prior analysis can lead to unnecessary data addition, making the problem worse. However, as humans, we are not good at processing large amounts of data quickly. More data is generally required for automation, but in manual production, it can lead to waste and inefficiency. The challenge lies in sorting and filtering existing data to make it more accessible to employees in a targeted manner.

Data is not always information

 control cabinet building

In digitalization projects involving people, it’s crucial to differentiate between data and information. The term data is used here as a generic term, regardless of its use, and information is the part of the data that is necessary or beneficial for the process. The implementation only considers data classified in the Information field, with redundant data included if necessary. Uniform implementation in the form of just a document, as is the case in production supported by paper documentation, is therefore not the optimal solution, as it can lead to the optimization of specialist processes. Paperless production is a welcome side effect of digitally supported optimization.

The path to Profinet with TSN

From |

The optimal network concept for artificial intelligence

Time Sensitive Networks (TSN) can revolutionize automation when combined with Profinet. Artificial intelligence (AI) in automation, such as ChatGPT, requires large amounts of data to be transported from the field to the AI system, affecting the control process. High-precision time synchronization is essential for processing and evaluating distributed data from the field level. TSN standards contribute to this, and the migration process is expected to be rapid. The combination of Profinet with TSN is ideal for meeting these requirements in a single network.

The path to Profinet with TSN

Currently separate networks for fieldbus and IT

Currently, requirements for optical anomaly detection using AI tools are implemented in separate networks due to limited transmission speed and high-precision time synchronization is also not currently available in IT networks and systems. This separation allows IT communication to maintain real-time capability, but also has costs and challenges in future extensions or changes. A “convergent network” can improve these functions by combining IT and OT disciplines in a single network, ensuring that the Ethernet structure, known as Time-Sensitive Networks (TSN), does not affect each other.

Currently separate networks for fieldbus and IT

TSN as a tool box for special purposes

TSN can be compared to a tool box containing several tools. Each of these tools serves a specific purpose. Here is a brief explanation of the tools:

Quality of Service (QoS) is crucial for real-time-critical traffic, while preemption reduces data forwarding variance. In addition, precision Time Protocol (PTP) is used for high-precision time synchronization in AI applications, allowing for microsecond-range synchronization accuracies. Synchronous communication ensures that terminal-to-terminal response time remains consistent. Brownfield integration is necessary for Profinet with TSN, as it requires new hardware in all devices involved. However, a smooth transition from Profinet RT to Profinet with TSN is feasible, as any existing Profinet device can be used at the TSN area boundaries. By combining these tools effectively, Profinet with TSN offers advantages without changing the look and feel of the network.

TSN as a tool box for special purposes

Areas of application for Profinet with TSN

Profinet with TSN offers benefits in applications like optical anomaly detection, vibration data, 3D images, frequency synchronization, alarm messages, and firmware updates. These tools can be used for Profinet communication between controllers and field devices without changing the application view of Profinet. OPC UA with pub/sub communication is more suitable for data exchange between different controllers. The OPC Foundation is working on a usage concept for TSN in OPC UA Field Exchange.

Comprehensive protection of the network

The IIoT trend has increased the need for better production transparency and control, leading to higher demands on access security. Phoenix Contact offers a Secure Edge Box to address these challenges. Data acquisition solutions often have different interfaces and communication protocols, making them confusing and difficult to administer. In addition, the diversity of solutions requires a high level of expertise, which may require external help. For this purpose, a standardized and secure remote connection to the peer must be set up. At best, a secure edge interface is established between manufacturing and other networks. To support users, Phoenix Contact offers a Secure Edge Box that solves the challenges listed..

Comprehensive protection of the network

Signal light for checking VPN connections

The Secure Edge Box is a tool used to protect production from attacks and sabotage by controlling data traffic and dividing the network into small areas. It uses an industrial firewall router, the mGuard firewall, to separate the lower-level network from manufacturing. In addition, firewall rules can be entered or managed centrally using the mGuard Device Manager tool. The box also allows remote VPN access, allowing employees to monitor the VPN connection status.

Additional security settings via a managed switch

The box features a second switch controlling the DMZ port of the firewall router, allowing service technicians to access specific devices in the area via this port. The mGuard firewall records the configuration through digital inputs. Additionally, if the control cabinet door is opened and there is a potential risk of tampering on site, the mGuard firewall can send an alert to a configurable receiver. A managed switch with 16 ports from the FL mGuard 2000 series is used for networking. Additional security settings can be made when configuring the switches, including user administration and authentication on RADIUS or LDAP servers.

Edge PC for data acquisition and forwarding to a cloud

The edge PC with PLCnext Runtime in the Secure Edge Box can be upgraded via the PLCnext Store, a digital marketplace for PLCnext Technology. It can implement local data acquisition with visualization and anomaly detection. In this way, for example, energy data or analog sensor data is transmitted to the edge PC via MQTT or OPC UA. With the second approach, the data is forwarded to an online hosted cloud. The edge PC normalizes, compresses, and stores data temporarily, ensuring compatibility with almost all systems. Both approaches can be used in parallel to increase data availability, and additional apps for data anomaly detection can be installed. Regulatory intervention in the process is also possible.
